The Jets are returning to full health as Sunday’s Week 3 game against Buffalo approaches.

At Thursday’s practice, rush outside linebacker Quinton Coples participated in position drills for the second straight day. Jets coach Rex Ryan said Coples got some work during team periods Wednesday, which is a positive sign for Coples. He is returning from a right ankle injury – reportedly a hairline fracture – that required surgery, but probably will play in a limited role against the Bills if he does indeed play, Ryan said Wednesday.

Wide receiver Jeremy Kerley, who missed the Week 2 loss at New England with a concussion, was out of a red (non-contact) jersey for the second straight day Thursday. Kerley has proclaimed himself ready for Sunday’s game. On Wednesday, he passed the NFL’s concussion assessment protocol and was medically cleared to return to practice.

Running back Bilal Powell returned to practice Thursday after missing Wednesday because he was sick. Powell has 25 carries for 77 yards and a touchdown this season, while Chris Ivory has 22 carries for 67 yards.

Santonio Holmes, the Jets’ best receiver, played 69 of 74 snaps at New England and said he came out of the game physically fine. On Thursday, he rode an exercise bike during the portion of practice that was open to reporters. The Jets are easing Holmes back after he underwent two offseason surgeries on his left foot.
